Math question: What is the smallest prime factor of the number 6661?

To find the smallest prime factor of 6661, we need to check if any prime numbers divide exactly into 6661. We start with the lowest prime number 2, but it is not a factor. Next, we try the next prime number 3, but it does not divide 6661 either. Continuing in ascending order, we check 5, 7, 11, and so on. Finally, when we reach 17, we find that 17 is a divisor of 6661. Therefore, the smallest prime factor of 6661 is 17.

Question: Find the sum of the digits of the number 6661, when each digit is multiplied by the sum of the digits of 6661, multiplied by the sum of the digits of the new number obtained, and so on, until a single-digit number is achieved.

To solve this, we start by finding the sum of the digits of 6661, which is 6 + 6 + 6 + 1 = 19. Now, we multiply each digit (6, 6, 6, and 1) by 19, which gives us 114, 114, 114, and 19 respectively. The sum of these new digits is 1 + 1 + 4 + 1 + 1 + 4 + 1 + 1 + 4 + 19 = 47. Again, we multiply each digit of 47 by 19, resulting in 893, 893, and 361. The sum of these digits is 8 + 9 + 3 + 8 + 9 + 3 + 3 + 6 + 1 = 50. Finally, we multiply each digit of 50 by 19, giving us 950. Since 950 has three digits, we continue until we have a single-digit number. Multiplying the digits of 950 by 19 gives 171, and multiplying the digits of 171 by 19 gives 243. Further multiplication gives 54 and 9. So, the final single-digit number achieved is 9. Thus, the answer to the question is 9.

Question: What is the sum of all the prime factors of 6661?

To find the prime factors of 6661, we perform prime factorization by dividing it iteratively by prime numbers. Initially, we divide by 2, but 6661 is odd. Trying 3, we get 6661 ÷ 3 = 2220 remainder 1. Not divisible by 5, 7, 11, or 13. Finally, by trying 17, we get 6661 = 17 × 391. Since both 17 and 391 are composite, we continue dividing until we find two prime factors: 6661 = 17 × 23 × 13. Now, adding all the prime factors together: 17 + 23 + 13 = 53. Thus, the sum of all prime factors of 6661 is 53.
